Homework Help: Fluid mechanics problem

  1. May 2, 2012 #1
    1. The problem statement, all variables and given/known data

    A horizontal bend in a pipeline conveys water at a discharge at 1000l/s gradually reduces from 600mm to 300mm and deflects the flow through an angle of 60 degrees. At the larger end the pressure is 170000N/m^2. Determine the magnitude and direction of the force exerted on the bend.

    2. Relevant equations
    How can I find pressure2 (at point 2 300mm end)

    is my solution right to find pressure at point 2

    Please help as i need solution urgently. Thanks to all

    3. The attempt at a solution

    I have used moment to find internal force F=DENSITY * FLOW DISCHARGE (V2-V1)

    Than I have used the formula F=P/A to find the pressure.


    P.s if i find p2 i can use formula to find external forces on the bend using
